(1) Maximum input voltage is limited to 24 V because of the package power dissipation limitations at full load (P ≈ (V_IN – V_OUT) × I_OUT =
(24 V – V_REF) × 50 mA ≈ 1.14 W). The device is capable of sourcing a maximum current of 50 mA at higher input voltages as long as the power dissipated is within the thermal limits of the package plus any external heat sinking.

(2) I_FB > 0 μA flows out of the device.

(3) For fixed output voltages only.

(4) For adjustable output only, where V_OUT = 1.2 V.
